Step-by-Step Instructions

Prep the Ingredients

1. Cook Chicken: Bake, boil, or use pre-cooked shredded chicken.
2. Make the Rice: Prepare according to package instructions. Leftover rice works great here.
3. Handle the Zucchini: Slice thinly or grate, then press with a towel to remove moisture.
4. Optional Aromatics: Sauté onion and garlic in oil for added depth.

Combine and Bake

1. Set your oven to 375°F (190°C).
2. In a large bowl, stir together all ingredients: chicken, rice, zucchini, cheese, soup, and optional sautéed vegetables.
3. Season with your favorite spices.
4. Transfer the mixture to a greased 9×13-inch baking dish.
5. Add extra cheese on top, if desired.

Cooking Tips

• Bake uncovered for 30–35 minutes.
• Look for a bubbling edge and golden top.
• Let cool for 5–10 minutes before serving to help it set.
• Sprinkle fresh herbs or a light drizzle of olive oil after baking for extra freshness.

Flavor Variations and Dietary Swaps

This recipe is easy to adjust based on taste or nutrition needs:

Gluten-Free / Low-Carb Options

• Swap rice with cauliflower rice for a low-carb alternative.
• Use a gluten-free cream soup or make a homemade version with dairy-free milk and cornstarch.

Spice Things Up

• Add jalapeños, chili flakes, or cayenne for a touch of heat.
• Stir in a few dashes of hot sauce or a spoonful of chipotle paste.

Explore Cheesy Alternatives

• Try pepper jack, smoked gouda, or even feta for a bold twist.
• Parmesan can be sprinkled on top for a nutty, crispy finish.

Global Inspirations

• For a Mediterranean version, add chopped kalamata olives and oregano.
• For a Tex-Mex twist, include black beans, corn, and taco seasoning.
• Try an Italian-inspired take with marinara instead of cream soup and a mozzarella-parmesan blend.
